| titleOfInvention | Fluorescent chemical sensor for detecting [H plus] and preparation method and usage thereof |
| abstract | The invention discloses a fluorescent chemical sensor for detecting [H plus] and a preparation method and usage thereof. The fluorescent pH sensor adopts 10,11,12,13-tetraphenylphenanthro[9',10':4,5]imidazole[1,2-a]pyridine or 9, 11,12,14-tetraphenyldibenzo[f,h]imidazole[1,2-b]isoquinoline as a fluorescent material, which is prepared into 1 multiplied by 10 to 5mol/l of standard testing solution,and when acidic solution is added into the standard testing solution, an ultraviolet spectrum can detect the increase of the intensity of an ultraviolet absorption curve and a fluorescence spectrum can detect the decrease of the intensity of a fluorescence emission curve and the response of emission peak blue shift. The invention is characterized in that: the standard testing solution is easy to prepare, consumption is little, the speed of fluorescence response is high, the amplitude is high, and common metal ions cannot interfere with the fluorescent chemical sensor. The fluorescent chemicalsensor can be used for testing the acidic sewage of chemical plants and acid food such as yolks, cream, tunas, flatfishes, cheese or soybean milk. |
